MAX823TEUK-T

Supervisors Overview

The MAX823TEUK-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 3.08V and an overvoltage threshold of 3.11V. The device features a manual reset function, a watchdog timer, and an active low push-pull output. It operates within a supply voltage range up to 5.5V and supports a reset timeout of 200ms minimum. The component is housed in a SOT-23-5 package and functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset capability via external input
• Features active low push-pull output driver

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded systems
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as 'T' typically indicates tape and reel packaging while variations may exist. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the specific batch matches the required operating temperature range and package variant for your design integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The SOT-23-5 package suits space-constrained designs. Verify that the 3.08V threshold aligns with the monitored rail and that the manual reset feature meets system control requirements. Consider the extended temperature range for harsh environments.

Supervisors Part Context

This part belongs to the MAX823 series of microprocessor supervisors. It shares functional similarities with other parts in the family but differs in package type (SOT-23-5) and specific electrical thresholds compared to variants like the MAX823YEXK+T which uses SC-70-5 packaging.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX823 series such as MAX823LEXK+T or MAX823YEXK+T, ensuring pin compatibility and threshold voltage alignment. Verify package equivalence between SOT-23-5 and alternative footprints before substitution.
